Approach – Measure Performance Didn’t look like mobile web was taking off until…

Good Screen Easy Navigation Unlimited Data Plan Can work with most normal websites It’s cool, people are buying it Mobile Web - HTML Why Is the iPhone a Game Changer?

Good Screen

Easy Navigation

Unlimited Data Plan

Can work with most normal websites

It’s cool, people are buying it

Mobile Web - HTML Increased Usage

Mobile Web - HTML Lots of Excitement

iPhone is still the platform to target Other (Microsoft, Opera, Nokia catching up) New players in the game http://developer.apple.com/webapps/ Mobile Web - HTML Increasingly Good Documentation

Approach – Measure Performance “ Text messaging on campus is replacing IM”

Campus Communication is HARD Increasingly distributed student population Traditional mechanisms loosing effectiveness Email volume has made it difficult to rise above noise Messaging Strategic Tie In

Campus Communication is HARD

Increasingly distributed student population

Traditional mechanisms loosing effectiveness

Email volume has made it difficult to rise above noise

Email Gateways Different between providers Uncertain SLA, reliability Message Aggregators Deliver to multiple networks, report status See Krishnan’s presentation later on this Messaging Message Delivery
